Technical Field

[0001] The utility model relates to a hardware accessory, in particular to a folding sliding door connector. Background Art

[0002] Folding sliding doors, also known as PD doors, require docking devices. These devices are widely used in modern buildings, especially in doors that require frequent opening and closing, such as office doors and conference room doors. However, existing PD door docking devices have some significant shortcomings, which bring great inconvenience to installation and use.

[0003] In existing PD door docking device designs, the relative height between the fixed and movable bases must be repeatedly adjusted to ensure accurate docking. This process is not only cumbersome but also prone to errors. Especially during initial installation, multiple adjustments are required to achieve a satisfactory docking effect, which invisibly increases installation complexity and time costs.

[0004] Furthermore, after a period of use, hinges and other connecting components can wear out, causing the relative height between the fixed and movable bases to change. Wear is inevitable, and this change can affect the door's proper function, requiring regular adjustments to the docking station to ensure proper function. This not only increases maintenance costs but also creates significant inconvenience for users.

[0005] Specifically, the existing PD door docking device has the following deficiencies: 1. Complex installation: The relative height of the fixed seat and the movable seat needs to be adjusted repeatedly, which increases the difficulty and time cost of installation.

[0006] 2. Difficult maintenance: Wear and tear of hinges and other connecting parts can cause changes in docking height, requiring frequent debugging and affecting user experience.

[0007] 3. Low docking accuracy: Due to the error of human adjustment, it is difficult to ensure high-precision docking between the fixed seat and the movable seat, which affects the normal opening and closing of the door body. Therefore, it is necessary to make further improvements. Utility Model Content

This high-precision docking method ensures the stability and reliability of the door during use, and avoids jamming or malfunctioning of the door due to inaccurate docking.

[0026] 6. The elastic buckle and locking groove design of this utility model provides a reliable locking mechanism. When the movable base and fixed base are docked, the elastic buckle retracts under the action of the extrusion slope, then rebounds and snaps into the locking groove, firmly locking the relative position between the two. This design ensures that the docking station remains stable even under external forces, preventing it from loosening or falling off, and improves the safety and durability of the overall structure.

[0027] 7. After the fixed seat and the movable seat are separated, the lock block extends into the movable guide rail groove to prevent the sliding door from moving in the non-docking state, ensuring its safety. BRIEF DESCRIPTION OF THE DRAWINGS

When the movable seat 2 is docked with the fixed seat 1, the guide boss 12 is inserted into the guide groove 22, and the elastic buckle 13 is snapped into the lock groove 23, thereby locking the relative position between the movable seat 2 and the fixed seat 1.

[0035] The side wall of the movable guide groove 21 is also provided with a locking groove 24, which is connected to the movable guide groove 21. A locking block 3 is slidably installed in the movable guide groove 21. The locking block 3 is supported by a spring and always pops out in the direction of the movable guide groove 21 and extends into the movable guide groove 21; an oblique pressure push block 31 is also provided on the locking block 3. When the movable seat 2 is docked with the fixed seat 1, the oblique pressure push block 31 and the fixed seat 1 squeeze each other to push the locking block 3 to retract.

[0036] In one embodiment, the locking groove 24 is an open groove that connects to the docking end surface of the movable seat 2 , and the upper and lower end surfaces of the open groove are provided with an arc-shaped transition introduction arc surface 25 .

[0037] In one embodiment, the locking groove 24 is an open groove, the surface of the open groove is covered with an end cover 6, and the end cover 6 and the open groove are enclosed to form a blind hole opening toward the movable guide groove 21, and the locking block 3 is slidably installed therein.

[0038] In one embodiment, the side wall of the locking block 3 is provided with a limiting protrusion 32 protruding from its end face. Correspondingly, a limiting groove 61 is provided on the end cover 6, and the limiting protrusion 32 extends into the limiting groove 61 to limit the movement stroke of the locking block 3.

[0039] In one embodiment, a mounting hole is provided at the tail of the locking block 3 , and the spring 34 is installed in the mounting hole.

[0040] In one embodiment, the oblique pressing push block 31 protrudes from the front end surface of the locking block 3 and extends into the movable guide rail groove 21 .

[0041] In one embodiment, the front end surface of the inclined pressure push block 31 is further provided with an extrusion slope inclined toward the movable guide rail groove 21 . When the movable seat 2 is docked with the fixed seat 1 , the fixed seat 1 and the extrusion slope are squeezed against each other, driving the elastic buckle 13 to retract.

[0042] In one embodiment, the docking surface of the movable seat 2 is a rear inclined surface that is wide outside and narrow inside. Correspondingly, the docking surface of the fixed seat 1 is a front inclined surface that is narrow outside and wide inside.

[0043] In one embodiment, a guide wheel 5 is rotatably mounted on the fixed seat 1 via a pulley seat 4, and correspondingly, a guide slope 7 is built into the movable seat 2. When the movable seat 2 is docked with the fixed seat 1, the guide wheel 5 and the guide slope 7 squeeze each other, so that the movable seat 2 is aligned with the fixed seat 1.

[0044] Working Principle: In this case, the fixed base is mounted on the door frame and is equipped with a fixed guide groove 11 and a guide boss 12.
